18 Claims.

The present invention relates to machines which are used in themanufacture of shoes to perform certain operations progressively alongthe bottom margin of a shoe, and is hereinafter disclosed as embodied inan edge trimming machine of the type in which the shoe and the edgetrimming devices are moved relatively to transfer the point of operationabout the shoe, and in which mechanism is provided for relatively movingthe edge trimming devices and the shoe to maintain the edge trimmingdevices and the shoe in proper relative positions at the point ofoperation as said point is transferred about the shoe. While theinvention is intended primarily as an improvement in automatic sole edgetrimming machines, certain features of the invention are capable of usein automatic machines for performing operations other than edge trimmingprogressively along the bottom margin of a'shoe. Certain features of theinvention also are capable of use in shoe machines which are notautomatic, and more particularly in nonautomatic edge trimming machines.

It is a principal object of the present invention to provide a templetconstructed and supported with relation to the shoe in a novel andimproved manner for causing the shoe operating devices to follow apredetermined contour line during the transfer of the operation aboutthe shoe, and to enable this operation to be performed in an accurateand reliable manner to secure satisfactory and uniform results withoutthe use of skilled labor, and notwithstanding irregularities in the shoecontoursor variations and imperfections in the shape or arrangement ofthe various parts of the shoe produced during preceding shoemakingoperations.

It is a further object of the invention to provide in an automaticmachine of the general type which includes shoe operating devices and ashoe supporting jack relatively movable to transfer said devices alongthe bottom margin of a shoe supported on the jack, a novel and improvedtemplet associated with the jack for determining the path followed bythe point of operation about the shoe constructed and arranged to permitthe operation of such devices both on the sole edge and upon theadjacent bottom portion of the shoe sole free from interference with thetemplet or its supporting structure.

It is a further object of the invention to provide a novel and improvedassembly of a shoe supporting jack and templet or other guiding meansfor determining the path followed by the point of operation about theshoe, which is well adapted to enable the operator by the simpleoperation of locating and locking the shoe on the jack at the same timeto locate the templet surely and accurately with relation to the shoe,so that the point of operation during the subse- 5 quent operation ofthe machine will follow a predetermined outline about the shoe.

It is a further object of the invention to provide, in a machine of thegeneral type which comprises shoe operating devices and a shoe sup- 10porting jack, a templet having guiding surfaces determined in accordancewith the size and style of shoe being operated upon for causing the shoeoperating devices during the transfer of the operation about the shoesole to follow a smooth and 15 regular outline irrespective of theirregularities in the contour of the shoe, in which the guiding surfacesof the templet are readily adjustable to cause the path followed by theoperating devices to conform generally to different widths of shoes. 20

With these and other objects in View as may hereinafter appear, aprincipal object of the invention consists in the provision of a templetcomprising two rigid arms pivotally supported adjacent the toe portionof the shoe supporting jack and arranged for engagement with sideportions of the shoe upper to secure an automatic adjustment of thecontour lines of the templet in accordance with the width of shoe beingoperated upon. 30

Another feature of the invention consists in the provision of a clampingdevice for securing the free ends of the templet arms against the sideportions of the shoe irrespective of the position of the shoe on thejack to insure the correct location of the templet guiding surfaces withrelation to the shoe sole.

The several features of the present invention consist also in thedevices, combinations and arrangement of parts hereinafter described andclaimed, which together with the advantages to be obtained thereby willbe readily understood by one skilled in the art from the followingdescription taken in connection with the accompanying drawings, in whichFig. 1 is a View in front elevation of an automatic edge trimmingmachine embodying in a preferred form the several features of theinvention; Fig. 2 is a plan view with a portion of the machine casingbroken away to illustrate underlying parts in the base of the machine;Fig. 3 is an enlarged view in right side elevation illustratingparticularly the shoe supporting jack, the templet, templet guide andedge trimming cutter; Fig. 4 is a plan View partly in section taken onthe line 4-4 of Fig. 3;

Fig. 5 is an enlarged view in front elevation of the shoe supportingjack and the templet with a shoe located in operating position thereon;and Fig. 6 is an end view looking from the left, of a portion of themechanism shown in Fig. 5, illustrating particularly the templet andclamping means for clamping the two arms of the templet in positionagainst the sides of the shoe.

The automatic shoe edge trimming machine herein disclosed as embodyingin a preferred form the several features of the invention, comprises amachine head 20 which has supported therein an electric motor providedwith a vertically situated armature shaft 22 which carries at its lowerend a rotary edge trimming cutter 24. The machine head 29 is bolted to abase 26 which provides a support for the driving and stopping mechanismgenerally indicated at 23, and serves as a housing for the jacksupporting and actuating mechanisms.

The shoe supporting jack herein disclosed is substantially thatillustrated and described in the application of Garrett P. S. Cross,Serial No. 584,325, filed January 2, 1932. The jack, as best shown inFigs.-3 and 5, comprises a vertically arranged spindle 35 having rigidlyformed on its upper end a frame 32 which carries the toe support 34.Cooperating with the frame 32 is an arm 36 which is loosely mounted on apivot stud 38 to swing toward and away from the toe rest, and carries atitsupper end a heel supporting lever 40 and a vertically situated lastpin 42 formed integrally with the lever, which are arranged for tiltingmovements toward and away from the toe rest about a pivot stud 44 on thearm 36. A spring 45 coiled about a pivotjstud 48 on the frame 32connected at one end to a pin 50 on the swinging arm 36, and at itsother end anchored in a central bore in the spindle 30, tends normallyto maintain the arm 35 in a relatively retracted position away from thetoe rest 34. The tilting movements of the heel supporting lever 4!! andheel post 42 are controlled through mechanism which includes a lever arm52 pivoted at 54 on the arm 36, and having formed on the hub thereof agear segment which meshes with a corresponding gear segment formed in adownward cxtensionof the heel supporting lever 46. A small tensionspring 56 connected at one end to a pinch the arm 36 and at its otherend to the lever 52, tendsnor'mally to tilt the heel supporting lever 40and heel post 42 in a counterclockwise direction as shown in Fig. 5,away from the toe rest.

In order to locate a shoe on the jack, the shoe supported on 'a last isfirst fitted onto the heel post 42, and is then forced forwardly anddownwardly by the operator to bring the 'shoe toe into engagement withthe toe support 34 where it is locked in position by the operation ofstopping and locking devices which are tripped into operation by theengagement of the shoe toe with a feeler 58, and act respectively toprevent further movement of the arm 36 toward the toe rest, and at thesame time to lock the arm 36, and heel supporting lever 40 and post 42,against movement in a reverse direction under the pressure ofjtheirrespective'springs, so that the shoe is jack frame 32.

locked in position on the jack. The stopping mechanism referred to,comprises a rack bar 62 pivotally secured at one end to the arm 36, andat its other end 'provided with rack teeth engaging with a pinion 64 ona rotatable shaft 66 on the There is' also mounted on the shaft 65 astop ratchet 68 which is arranged to be engaged by a stopping detent H3when rendered operative by the tripping of the feeler 58 to arrestfurther movement of the arm 36 toward the toe rest. The mechanism forlocking the parts of the jack in the position illustrated in Fig. 5,comprises a locking rack bar i2 pivotally secured at one end to thelever arm 52, and at its other end provided with a rack arranged forengagement with a pinion i4 mounted'on a rotatable shaft 16 on the jackframe 32. to the shaft 76, a ratchet T! which is arranged for engagementwith a locking detent 18 when rendered operative by the engagement of ashoe toe with the feeler 58. Inasmuch as the construction and mode ofoperation of the stopping and locking devices thus far described,together with the mechanisms for controlling the operation of thestopping and locking detents if) and "[8 respectively from the feelermember 58, are fully illustrated and described in the Cross applicationabove referred to, and form specifically no part of the presentinvention, a further description of these mechanisms is believedunnecessary.

The jack illustrated is also provided with toe clamping devices forlocating and rigidly clamp- There is also secured ing the toe portion ofthe shoe in adjusted position laterally of the jack. These devices, asillustrated in Figs. 3 and 5, and as more fully described andillustrated in the Cross application above referred to, comprise two toeclamps and 82 which are carried respectively on two carrier arms 84 and86, and are arranged for engagement with opposite sides ofthe shoe upperadjacent the toe of a shoe supported on the jack. Each of the carrierarms 34 and 3G is shaped to extend downwardly and horizontally, so thatthey are located parallel and in close proximity to each other under thetoe rest 34. The carrier arms 84 and 86 and toe clamps 8-3 and 82carried respectively thereon, are mounted to move toward and away fromeach other substantially in planes inclined downwardly toward the centerline of the jack, the carrier arm 86 being pivotally secured at 88 to anupwardly extending H-shaped lever 90 pivoted at 92 on the jack frame,and the carrier arm 84 being supported at 94 on alink 96 which isarranged to turn on a fixed pivot 98 'on the jack frame. In order tocontrol the position of the carrier arms 84 and 86, and also to providean additional support therefor, the carrier arm is provided with adownwardly extending portion I510 journalled to receive a pivot pin I02in one arm of a bell-crank lever I04 pivoted at I05 on the jacl; frame.The

two ends of the pivot pin Hi2 are flattened to engage with slots formedrespectively in the downward extending arms of the H-shaped carrierlever 96, so that a movement of the bell-crank I04 about its pivot, actsto move the carrier arm 84 and 'toeclamp'fiil inwardly or outwardly asthe case may be, and acts simultaneously by rocking the carrier lever9i) about its pivot 92 to impart corresponding inward or outwardmovements to the carrier arm 86 and toe clamp 82. The carrier arm 85ismaintained in proper angular position during relative movements of thecarrier arms and toe clamps above described, by means of a boss I08which projects laterally from the carrier arm 84 and engages with aguideway H0 formed in the horizontal extension of the carrier arm 86.

After a shoe has been located upon and locked in position on the jack asabove set forth, the toe clamps'are moved into clamping engagement withthe toe portion of the shoe upper, to locate the toe laterally of thejack, andan additional rotative movement is imparted to the lockingratchet I4 and associated parts to tighten the jack by forcing the shoetoe downwardly into firm engaging contact with the toe rest 34 by theoperator, through the manipulation of a manually operable clamping leverII2 which is loosely mounted to turn on the pivot stud 48 on the jackframe 32. Connected to the clamping lever I I2 is a link II4 which issecured at its upper end to an intermediate point on a cross lever II6which operates when moved downwardly by the actuation of the clampinglever 2 through mechanism connected to one end thereof, to move the toeclamps 80 and 82 into clamping engagement with the shoe toe, and throughmechanism connected to the other end thereof, to

impart an additional movement to the locking ratchet I4 and associatedparts, to tighten the jack. One end of the cross lever H6 is pivotallyconnected at H8 to a U-shaped lever I20 which is supported to turn ontwo studs I22 on the jack frame 32, and is connected through a link 224to a horizontally extending arm of the bellcrank lever I04 forcontrolling the operative positions of the toe clamps 80 and 82. Theother end of the cross lever H6 is connected through a, link I26 to thetail portion of a pawl I28 which is pivoted on a pawl lever I30 mountedto turn freely on the supporting shaft I4 for the ratchet I6. A tensionspring I32 connected between an extension on the pawl lever I30 and apin I34 on the jack frame 32, tends normally to maintain the lever I30and pawl I28 in a fully raised or retracted position. A tension springI36 se-' cured at one end tothe manual clamping lever H2 at the point ofconnection with the link II 4, and at its other end on a pin on the jackframe; tends to swing the lever in a counterclockwise direction as shownin Fig. 5, to a normally retracted rest position. The operation of themanually operable clamping lever II2 first to move the toe clampsi80 and82 into clamping position, and thereafter to impart an additionalmovement to the ratchet I4 to tighten the jack, may be described asfol-' lows:- I Assuming that a lasted shoe has been'placed on the lastpin 42, and the shoe then moved forward to engage the shoe toe with thetoe rest 34 and feeler 58 so that the stopping and locking detents I andI8 are rendered operative to lock the shoe in the jack, the operator nowmoves the manual clamp lever II 2 sharply upward in a clockwisedirection as shown in Fig. 5, causing the link II4 and intermediateportion of the cross lever I I6 connected thereto to be moveddownwardly. Since a considerable resistance is provided to the movementof the left hand end of the cross lever II 6 and pawl mechanism abovedescribed, by the spring I32, the cross lever I i6 will turn about itspivotal connection with the link I26 to swing the U-shaped lever !28downwardly, and, acting through the link I24 and bell-crank I04, willmove thetoe clamps 80 and 82 into clamping engagement with the side toeportions of the shoe upper, so that the shoe is firmly held in anadjusted position laterally of the jack. The toe clamps are positivelylocked against movement relatively away from each other by means of alocking device not here shown, which is identical with that illustratedand described in the Cross application above referred to. I

The continued turning of the manual clamping:lever:II2 now causes thecross lever II6 to turn about its pivotal connection with the lever I20as a fulcrum, to move the pawl I28 and pawl lever I30 against thepressure of the spring I32 into engagement with the locking ratchet 11,80 that an additional movement is imparted thereto to draw, the lockingrack I2 toward the toe' portion of the jack, to secure the desiredtightening effect.

The devices for supporting the jack and for imparting thereto therequired feeding, turning and tipping movements to feed and to positionthe shoe with relation to the shoe operating devices to transfer thepoint of operation about the shoe, ;are substantially those well knownin the art, as illustrated, for instance, in the patent to Alfred.R.-:Morrill, No. 1,952,770, dated March 27, 1934, but may be brieflydescribed as follows: The jack supporting mechanism as generallyillustratedin Figs. 1, 2, and 5, comprises the jack spindle 30 which isconnected at its lower end by means of 'universal connections to turnwith a pulley I48 which is supported on the end of a forwardly extendingjack supporting arm I42. The supporting lever I42 is pivotally supportedfor vertical swinging movements on a lever I44 which-is carried on avertical pivot post on the upper end of a frame I46 which is in turnpivotedfor swinging movements forward and back on twoipivot studs I48supported on the base 26. The frame I46 is moved forwardly and back to-.provide the necessary roll tipping movements tothejack and shoesupported thereon about the point of. operation, by means of connectionscomprisinga lever arm I50 which is rigidly secured to a sleeve hub I52on a vertically extending pivot post I54, and at its free end isconnected by a short link to the frame M6. There is also rigidly securedto the sleeve hub I52, a cam lever I56 which carries a cam roll I58arranged for engagement with the roll cam I60 on the pattern cam shaftI62 of the machine. Lateral swinging movements are imparted to the leverI44 toimpart the required longitudinal or pitch tipping movements to thejack and shoe supported thereon about the point of operation, thrbughconnections which comprise an arm I64 rigidly secured to a downwardlyextending tail of the lever I44, and connected through a link I66 to alever arm I68 which is rigidly secured to. a sleeve hub II0 on thevertical pivot post I54. Secured tothe sleeve hub H0 is a cam lever I72which carries a cam roll I14 arranged for engagement'with a pitch camI16 on the pattern cam shaft I62. Rotational or turning movements areimparted to the jack through connec' tions including a cord or cable I78which passes around the pulley I40 and an idler pulley I85 on the rearend of the arm I 42, and is secured to apulley I82 supported on avertical pivot E84 on'the base 26. A pinion I86 formed on a sleeve hubof the pulley I82 is arranged to mesh with a-corr'esponding gear segmentformed on a lever I88 sleeved ,on the vertical pivot shaft 554. There isalso "secured to the sleeve hub of the lever I88, acam lever I90 whichcarries a cam roll I 92 arranged for engagement with a turn cam I94 onthepattern cam shaft I62. The required feeding movements are imparted tothe jack to transfer the point of operation along the margin of the shoesole, by means of a feed lever I96 which is supported at its rear end ona vertical stud I98 on the base 26,and at its forward end is connectedby means of a feed link 280 to the toe portion of the jack. The feedlever is connected through links 202 and 284 to one arm of a cam feedlever 206 which is supported on a pivot stud 268, and has mounted on theother arm thereof a cam roll 2) arranged for engagement with the feedcam 212 on the pattern cam shaft I62. The jack is further supported tomaintain the jack and shoe supported thereon in cooperative relationshipto the shoe guiding and operating devices, by means of a link 2l4 whichis pivotally connected at its rear end to a bracket 216, and at itsforward end is connected by means of a universal joint to the upperportion of the jack spindle 30. Inasmuch as the details of theconstruction and mode of operation of these mechanisms to impart therequired feeding, turning and tipping movements to the jack, are wellknown in the art, no further description thereof is believed necessary.

In accordance with the present invention, novel and improved guidingmeans are provided comprising a templet and templet guide for guidingthe shoe with relation to the operating devices as the point ofoperation is transferred about the shoe, to cause the operating devicesto follow a predetermined outline around the margin of a shoe. To thisend, a templet of novel and improved design is provided associated withthe jack and shoe mounted thereon, which is arranged for engagement witha relatively stationary templet guide mounted on the Work head 20 toengage with the templet at a point closely adjacent the point ofoperation of the shoe operating devices. As best shown in Fig. 30f thedrawings, the templet guide comprises a vertically extending plate 220which provides a point of contact with the templet directly beneath andsomewhat to the rear of the point of operation of the shoe operatingdevices, and is curved laterally away from each side of a centralvertical line to maintain the correct operating relationship between theoperating devices and the margin of the shoe sole during the turningmovements of the jack. The templet guide or plate 226 is formed on theforward end of a slide support 222, mounted for sliding adjustment in agroove 224 formed in the under side of a support 226 which carries theusual crease guide 228, being adjustably secured thereto by means of aclamping screw 236 which extends through a slot 232 formed in thesupport 222. The crease guide support 226 is in turn supported for aforward and back adjustment on two downwardly extending lugs 234 and 236formed on the under side of a bracket 238 secured to the machine head20. The support 226 is slotted at its rear end 'to receive a clampingbolt 239 screw-threaded into the lug 236, and at its forward end isarranged for sliding engagement in a guideway formed by two downwardlyextending arms of the lug 234. A slight vertical adjustment of thecrease guide 228 is obtained by means of a pin 24!] which is providedwith an eccentric middle portion fitted into a transverse bore in theslide 226, and has its ends engaging with slots 242 formed in the twoarms of the lug 234.

In accordance with a principal feature of the present invention, thetemplet herein disclosed is located with relation to the shoe in itsinverted position on the jack, below the level of the shoe sole and outof contact therewith, to permit a free operation of the work operatingdevices upon the edge of the shoe sole, and where so desired, upon thebottom surface of the shoe sole.

The jack actuating pattern cams of the present machine including thefeed, turn, pitch and roll cams above described, are formed withrelation to the guiding surface of the templet so that the shoe will becorrectly positioned with relation to the edge trimming cutter at alltimes during the progress of the operation about the shoe to trim thesole edge cleanly and accurately to the desired shape.

As best shown in Figs. 3, 4, 5, and 6 of the drawings, the templetcomprises two fiat plates 246 and 248 which are located respectivelyalong each side of the shoe, and have their outer edges shaped toprovide a contour surface corresponding substantially to the outline tobe followed by the operating devices during the operation around theshoe. Adjacent the toe portion of the shoe, the plates 246 and 248 arearranged to overlap, and are pivotally supported on the jack by means ofa pivot stud 250 mounted in a bracket 252 secured to the frame 32.

In accordance with one feature of the present invention, the templetplates 246 and 246 are arranged at their heel ends for clampingengagement with the shoe upper, so that the templet is located in apredetermined relationship to the shoe independently of any variationswhich may exist in the location of the last pin socket in the last, andalso in a position which will correspond exactly to the width of shoebeing operated upon. The templet plates 246 and 248 are supportedvertically with relation to the shoe and are clamped to the shoe upperadjacent the heel by'means of two clamping levers 254 and 256 which arepivotally supported at each end of a cross arm 258 formed integrallywith the heel supporting lever 40, and are arranged for supportingengagement respectively with the under sides of the templet plates 246and 248, and for clamping engagement with two clamping plates 26!! and262 secured respectively to the templet plates 246 and 248. The clampingplates 260 and 262 are each provided with vertically disposed surfacesfor engagement with the shoe upper, and at their heel ends withoutwardly extending flanges which are arranged, during the opening ofthe jack, to engage with the clamping levers 254 and 256 and limit themovement of the heel supporting arm 36 and last pin lever 46 away fromthe toe portion of the jack. With this construction and arrangement ofthe parts, the clamping levers 254 and 256 are maintained at all timesin operative relationship to the templet arms and clamping plates, sothat after a new shoe has been placed in the jack, it is necessary onlyto move the clamping levers into clamping position to locate the templetin adjusted position with relation to'the shoe. The clamping levers 254and 256 are connected at their lower ends by means of two toggle links264 and 266, and are normally moved relatively apart to maintain theclamping' levers in an open retracted position by means of a tensionspring 268 connected across the lower ends of the clamping levers. Inorder to bring the clamping levers 254 and 256 into clamping engagementwith the clamping plates 260 and 262 to clamp the templet plates 24-6and 248 in adjusted position, a manually operable lever 210 is provided,pivoted at 212 on the heel arm 36, and provided with a bearing surface274 arranged, upon an upward movement of the lever, to engage with acurved surface formed on. the toggle link 266 immediately beneath theconnecting pivot 218 for the two links, to straighten the toggle againstthe pressure of the spring 268, so that the clamping levers are movedpositively into clamping position. In order to hold the parts .inclamping position, a detent plunger 28!! is mounted in a bore 282 in thehandle of the lever 21s for engagement with asaw tooth ratchet 28 imounted on the heel supporting arm 38. A compression spring 286 seatedin the bore 282 and engaging the rear end of the plunger 28s, actsnormally to maintain the detent plunger in looking engagement with, theratchet 28 i. A pin 288 secured to the plunger 28:] and projectingoutwardly through a slot 290 in the lever 210, provides .a convenientmeans for withdrawing the detent 280 to permit the release of the lever2m and clamping levers 25d and 256 when it is desired to remove the shoefrom the jack.

With the construction and arrangement of the templet and jack associatedtherewith herein illustrated and described, only a simple operation isrequired to enable the operator quickly and accurately to locate andclamp a shoe on the jack and to secure the templet in adjusted positionwith relation to the shoe. The locating of the shoe longitudinally onthe jack as determined by the engagement of the shoe toe with the feeler58, serves also to locate the templet, secured to the toe supportingframe 32, longitudinally of the shoe sole. The subsequent operation ofmoving the toe clamps into clamping engagement with the toe portion ofthe lasted upper in tightening the jack, serves to locate the toeportion of the shoe laterally of the jack, and also laterally withrelation to the templet mounted on. the jack. The two arms 246 and 248of the templet are thenbrought into clamping engagement with the heelportion of the shoe upper to secure the templet finally in adjustedposition with relation. to the shoe, by the operation of the manualclamping lever 210 which operates through the straightening of thetoggle links 284 and 266 to move the clamping levers 254 and 256 intotight clamping engagement with the plates 26!! and 262 against thelasted upper. It may be noted at this point that the arrangement of theclamping levers 254 and 256 is such as to permit a free adjustment inthe clamping position of thelevers laterally of the jack, so that theywill be brought into tight clamping engagement with the shoe, causingeach of the templet plates 246 and 248 to be held accurately in.position against the shoe upper, irrespective of any possible variationsin the lateral positioning of the shoe heel which might result frominaccurate location of the last pin socket in the last.

With the construction and mode of mounting the templet with relation tothe shoe herein disclosed, the templet automaticallyadjusts itself tothe width of shoe placed in the jack, so that only one templet isrequired for all widths of any given size and last of shoe. Inasmuch asthe templet plates 2% and 2 88 are of rigid construction, theproportions and length of the outline followed by the shoe operatingdevices along each side of the shoe, are necessarily constant. As theheel portions of the templet plates 246 and 248 are brought closertogether for operation upon progressively narrower widths of shoe, theoutline followed by the operating devices along each side of the shoestarting fromy the shoe toe, will follow a progressively narrower pathas the shank portion of a shoe is reached. This variation in outlinefollows substantially the change in shoe outline of progressivelynarrower sizes, since in progressively narrower sizes, the

width of the shoe sole adjacent the toe portion of the shoe showsrelatively little change, whereas, increasingly marked diiferencesappear in width of the sole as the shank and heel portions of the shoeare reached.

The construction and mode of assembly of the templet herein disclosed,has the particular advantage that the templet is located entirely fromthe lasted shoe upper, so that the outline followed by the shoeoperating devices about the margin of the shoe, must correspond exactlyto the location of the lasted upper to insure a correct proportion ofall the parts of the finished shoe. This is of particular importance inconnection with the edge trimming operation for which the presenttemplet is particularly intended.

The location of the templet at a level considerably below and outsidethe sole of the inverted shoe on the jack, has a specific advantage inproviding adequate space for the operation of devices which act upon themargin of the shoe sole, and also where desired, upon the bottom 01 theshoe sole. This arrangement of the templet makes possible the use of atemplet in forming a channel in the shoe sole, so that the templet maybe utilized, for instance, in connection with machines which areconstructed and arranged for simultaneously performing an edge trimmingand channeling operation.
